Thermal stability of salt hydrates of sodium cation namely sodium hydroxide monohydrate, sodium acetate trihydrate, sodium thiosulfate pentahydrate, sodium carbonate decahydrate, sodium sulfate decahydrate and di-sodium hydrogen phosphate dodecahydrate has been evaluated at elevated temperatures using thermogravimetric technique. The energy of activation of dehydration of these salt hydrates have been reported. A new criterion based upon the ratio of percent water loss and energy of activation has been reported to determine the relative thermal stability of sodium salt hydrates.
